Abstract

Background and Objective: The advantages of millet and soybean strip intercropping in order to increasing beneficial use of environmental resources in weed-infested conditions.

Materials and Methods: A split-plot experiment was investigated in 2021 and 2022. The main plots included two weed-free and weed-infested treatments, and the subplots included eight intercropping and sole crop of millet and soybean.

Results: The effect of weed infestation, intercropping and their interactions on economic yield of both species were significant. The highest grain yield of millet (1134/83 kg/ha) and soybean (1832/83 kg/ha) were obtained in the weed-free sole crop treatment, and the lowest one in millet (355/16 kg/ha) was observed in 2M2S in weed-infested treatment and in soybean (440/22 kg/ha) was observed in 2S4M in weed-infested treatment. The highest LER (1.85) was observed in 2M4S in weed-infested condition, the maximum CAI in 2M4S intercropping in weed-free treatment and the maximum IA was related to 2M4S in weed-infested condition.

Conclusion: LER and CAI greater than one, indicates the superiority of millet and soybean intercropping, compared to their sole crop. The positivity of IA and AYL in intercropping treatments indicates the beneficial effect of species on each other in weed-free and weed-infested conditions. 2M4S intercropping in weed-infested treatment increased the yield of millet and soybean by 20% and 9.7%, respectively, compared to the sole cropping treatment of both plants in weed-free conditions.
